In some cases, it has outperformed popular diabetes drugs, including Metformin.

There is also some evidence that Spirulina Extract can be effective in humans.

In a study of 25 patients with type 2 diabetes, 2 grams of Spirulina Extract led to an impressive reduction in blood sugar levels.

HbA1c, a marker for long-term blood sugar levels, decreased from 9% to 8%, which is substantial. Studies estimate that a 1% reduction in this marker can lower the risk of diabetes-related death by 21%.

However, this study was small and only lasted for 2 months, so take this with a grain of salt.

11. Anything Else?

Spirulina Extract may also have other beneficial effects, such as helping to "detoxify" the heavy metal arsenic from the body.

At the end of the day, Spirulina Extract is incredibly healthy. It is one of the few "superfoods" that are actually worthy of that term.
